Vertebral Augmentation Vertebral augmentation, or kyphoplasty, is a minimally invasive treatment that can repair spinal fractures caused by osteoporosis, cancer or benign lesions. Spinal fractures can result from something dramatic like a fall, or from simple movements like coughing, sneezing or turning in bed.
Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds.
Surface Water: Water present on the surface of the earth in the form of oceans, rivers, lakes, ponds and streams is called surface water. The water in rivers and lakes comes from rain and melting of snow on mountains. Rivers flow into the sea. Some of the rainwater seeps through the soil on to the non-porous rocks below.
